YBO-BS is an addressable loop-powered base siren innovatively designed to provide a range of tones and volumes with a maximum output of up to 98 dB(A) (±2 dB(A)) with low current consumption.

It is designed to fit the standard (YBN-R/3) or isolator base (YBO-R/SCI) and can be equipped with any sensor, beacon or remote indicator from the ESP range.

It has a IP21 protection rating and is for internal use only, and can be converted to a wall siren with the cover (SI/CAP).

Auto-off function allows the user to set a fixed time within which the siren will operate before automatically silencing, reducing noise pollution.

  • HOCHIKI
  • Intelligent analog base siren
